A bulb thermometer gives an indoor temperature reading of 21 degrees celsius A digital thermometer in the same room gives a reading of 20.7 degrees celsius Which device is more precise?
The digital thermometer is more precise because it can measure temperature to one-tenth of a degree (20.7 degrees), while the bulb thermometer can only measure to whole degrees (21 degrees). The difference in precision is due to the digital thermometer's ability to provide more detailed readings.
Tool used to measure the temperature?
Whilst a thermometer may give an 'estimated' readout of which can be right within a few percent of the actual value, this is not very accurate at all. There are of course several different types of thermometers. Some made with quicksilver. Others made with alcohol. With the development of transistors, we started to develop electronic thermometers of which can work in many different ways. they can measure infrared radiation. they can measure intensity and spectrum of light. they can measure with probes of various metals. The art of measuring temperature is a difficult one. Most thermometers only work accurately within a short range. You would for instance not use a thermometer filled with quicksilver or alcohol in order to measure the temperature in a pot of molten lead! First you need to narrow down the field, then you can begin with the right (mostly costly) thermometer for the task. A piece of copper wire can be used in order to measure temperature between -200 and + 150 degrees Celsius. We know that the resistance in copper changes with a certain percentage per degree Celsius. With a bit of calculations we will be able to calculate the temperature to almost perfection if we only know the exact dimensions of the copper wire used. Whilst our best mathematical efforts show possibilities, we still have to be sure that we measure the resistance to a very high degree of perfection too, but this is another subject.
Explain how a barometer and a thermometer are alike?
A thermometer and a barometer are alike, because a thermometer tells temperature, and a barometer tells air pressure. They sort off connect, because when you have lower air pressure, you get colder temperatures and when you have higher air pressure, you know then that the temperature will be hotter. You can kinda tell by looking at only one piece of data, what the other piece might be. I'm pretty sure that's right, I'm only in 7th grade.
Why does wrapping cotton wool around a thermometer cause the temperature to drop?
Wrapping cotton wool around a thermometer can cause the temperature reading to drop because cotton wool is a good insulator. It prevents heat from reaching the thermometer, resulting in a lower temperature reading.
What are precautions that are to taken while measuring the temperature in clinical thermometer?
the mercury should be at normal body temperature level before using it the thermometer should be cleaned after use with normal water the bulb of the thermometer should not be touched

Is the best type of meat thermometer digital or analog?
Both are perfectly acceptable. A digital thermometer may measure to a tenth of a degree, but this is of no importance when cooking meat. What matters is that the meat gets to the necessary USDA-recommended internal temperature, and for this an accuracy of only a few degress is required. The only exception to this would be an analog thermometer that can be left in the meat during cooking, because the electronics and cases of digital thermometers can't take the heat.
What are the uses of thermometer?
Only one use, measure temperature
What the uses of thermometer?
Only one use, measure temperature
Can a sensible heat and latent heat transfers be read with a thermometer?
yes
Difference between clinical and a laboratory thermometer?
A clinical thermometer can only measure human body temperatures since it can measure no less than 35 degrees celcius and no more than 42 degrees celcius. An ordinary thermometer can measure and object or substance at any temperature.

Why are decimals used on thermometer?
To measure temperatures to an accuracy greater than only whole degrees.
Can you measure a dogs temperature in their mouth?
Yes, you can measure a dog's temperature in their mouth by using a digital thermometer. Place the thermometer under the dog's tongue and hold it in place for about a minute to get an accurate reading. However, measuring a dog's temperature rectally may provide a more reliable and accurate result.
Why was this thermometer made to measure only temperatures in this narrow range?

What is a clinical thermometer?
A clinical thermometer, this type of thermometer is sensitive to very small changes in temperature but is able to measure temperatures only within a few degrees of normal body temperature (thirty seven degrees celsius).
What is the purpose of a dual scale thermometer?
Some people want to measure temperature in deg C while others prefer deg F. A dual scale thermometer will allow people to do what they prefer, but using only one thermometer.
How do you check someone's temperature without a thermometer?
The only way to get an accurate reading of someone's temperature is to use a thermometer. They're easy to pick up from your local pharmacist - a traditional one will be relatively cheap whereas a digital one may cost a little more. If you have a fever, basic symptoms are chills and sweats but it's always useful to get it checked.
